Question

I have a two versions of my application layout, which are differs only in a few lines. Consider following example:

!!!    
%html
    %head
        # a lot of code here
%body
    # some more code here
    - if defined? flag and flag == true
        # variant 1
    - else
        # variant 2

The question is, how do I pass this flag to the layout?

class ApplicationController < ActionController::Base
    layout 'layout', :locals => {:flag => true} #won't work :(

    # ...
end

Answer 1

A controller instance variable? That’s the normal way to get information to the template.
